I've used Combro since about 1999 and it has had two new cases. Both times shot off having been lent out. I get them to bring their guns to me now! In the early days they fixed them for free but they are still cheap to repair. The yellow alignment tool wasnt available originally and you were advised to align by eye and if you were uncomfortable with that they offered a refund. Amazing British SME.

They still use serial interface technology. Has anyone successfully automated Combro on USB and particilarly on Macbooks?

Hi Y'all I see there's a few members with, or have tried a Combro chronoscope.

I just wondered what the general feeling was, regarding peoples experience with them. I've just bought a Mk4 version with the alignment tool just to make sure I was setting it up correctly. The no's I'm getting are lower than a couple of fairly random checks I've had done at our club, but it does seem to give fairly consistent results.

Any thoughts and experience would be appreciatedCheers Roj ( TX200HC )

Hi Moulindu - It's can be the sudden jerk when the barrel snaps shut that breaks the Combro body - that happened to me with my HW99. Be very careful when you (or your ex-friend) close the barrel, and support the Combro with your hand or it might happen again.

I have done a lot of work cross-calibrating umpteen Chronos lately, including Skans, Caldwells, Shooting Chrony's, F1's, R2's and a Bluechron (the Mk 1's were very good btw) and found that the Combro is as reliable as anything else for moderated PCP's but less good for anything with an air stripper/muzzle brake, when it can give seriously erratic readings. It is good with springers provided it is secured really tightly to the barrel so it can't move (and you don't break it ).
